Since 2019, 400G has become a hot topic in the optical communications industry. Several leading optical module manufacturers in the world have launched their own 400G optical modules and most of them have adopted QSFP-DD packages. As early as March 21, 2016, the QSFP-DD MSA team began to plan to develop the QSFP-DD high-speed interface, and experienced the resolution of a series of issues suc...
A router is a hardware device that connects two or more networks. It acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. Routers can be divided into backbone routers (core routers), enterprise-level routers, and access-level routers. Generally, backbone routers have multiple optical ...
As a switch brand equipment manufacturer, HP's equipment supports a variety of optical modules with different specifications. Users can choose the appropriate optical module according to their needs. Common optical modules are 100G QSFP28, 40G QSFP+, 25G SFP28, 10G SFP+ and 1.25G SFP etc. Below, ETU-LINK will give you a list of some commonly used HP optical module models. HP 1.25G SFP dual fiber s...
Two important development trends of optical modules are to increase the transmission rate and extend the transmission distance. However, as the transmission rate increases, the signal transmission distance will be limited by many factors, such as chromatic dispersion, nonlinear effects, and polarization mode dispersion. These factors will limit the increase in transmission rate and trans...
With the mature development of 100G technology and the advent of 100G products, the deployment of large enterprise network and data center is evolving towards 100G. At present, 100G optical modules on the market include CFP, CFP2, CFP4, QSFP28 and CPAK. The sizes of 100G optical modules in different packages are different. Among them, the 100G optical module in QSFP28 package has the smallest...
Now various industries are gradually inseparable from the existence of electricity, because every kind of electrical appliance needs electricity to operate. But once our phones, network video and wireless routers are out of power for no reason, where should we find a suitable power supply system? So the poe switch appears, a typical Ethernet power supply system, which is better suited to the ...
The QSFP28 package has become a mainstream 100G optical module with smaller size, power consumption and price advantages. In practical applications, how should we solve the interconnection requirements of 100G ports and 40G, 25G, and 10G ports? Below, ETU-LINK will introduce several common solutions to you. QSFP28 port interconnects with QSFP+ port We need to change the switch port configur...
With the rapid advancement of the 5G bearer network process, the demand for industrial-grade optical modules is increasing. The introduction of the 10G BiDi SFP+ ZR industrial module has enabled a new optical module solution for the construction of long-distance metropolitan area networks. Next ETU-LINK will briefly introduce the 10G BiDi SFP+ ZR industrial optical module. &nbs...
